LINER FOR TIRES.

Application led November i3, H13.

the pneumatic type; and the object'of theA same is to improve the construction of such a liner which is to be interposed between the ycasing and the tube. This object is carried out in the manner hereinafter described and claimed, and as shown in the drawings Whcrein Figure l is a side elevation -of a liner involving this invention. Fig. 2 is an enlarfred cross section through the liner laid out flat.

"ig 3 is a section through the liner in position between a tube and its casing. Fig. 4 is a plan View of a portion of the liner, Viewed from the inside.

Ordinarily this liner is intended to be disposed between 4the casing C and the air tube T, although its use is notl limited in that respec-t because it might be strapped around a. casing if the latter were sulliciently small or it could be strapped around a single-tube tire such as is sometimes used on bicycles.

' In fact, if made in short sections it might be used as a repair shoe, as the mnner in which it is fastened in place permits it to' expand Within limits. In the following specification, however, I will describe it as a. liner whose function is to protect the rubber air tube'T from perforation by a nail or other obstruction whichI might pass through the outer tire C.

The `body of this lining is made of two members. The innermember is two-ply, its sheets 1 and 2 being of strong, smooth, closely-woven and impenetrable fabric, with a non-combustible sheet 3 of asbestos or the like between them, and the threethicknesses stitched together as at 4. The outer mem` is made of substantially the same ma- 2l as the sheets l and 2 excepting that icker, one edge is laid over the threef ...u member as si o. and thencarried around the side edge thereof as at 7, the two members being connected by parallel e s .mi

lines 8 of stitching7 and a row passed through the members between said es. Thc other edge of the outer melmbcr is carried around the opposite edge of 'the inncrnmember as at 17, secured thereto l stitching 1.8, and 'has a row fr two lincs of of eyelets 19 between the lines; and the edge of the outer member beyond the innermost line of stitching is left free at to constitute a flap. The edges of the device Vthus formed are adapted to be connected by straps, or preferably by a lacing as indicated at 20. the same passing througheyelets 9 and 1S). In the manufacture of this device the outer member is made a little fuller than the inner member, both transversely and longitmlinally of the tube,` and therefore a space exists between said members as indicated in Fig. 3.

This liner is applied to an inner tube T by passing it around the same and lacing it as will beclearly understood, leaving the valve stem to project from the inner side of the tube at a point between the edges of thc liner. The t-ube is then inserted in the casing C and the casing put o n the Wheel, and finally the tube is infiated by the usual or any welllinown process until it is tight within the inner section of the liner. The fact that' the asbestos or non-combustible sheet is interposed between the 'two sheets l and Q ofthe. inner section renders this device non-intlaihmable. The fabric of which these sheets` and the single and thicker sheet composing the'v outer member is made -is treated to render it water-proof, heat-proof,

sand-proof, bloW-out-proof, and punctureproof; but the .details of the process by which it. is so treated form no part of the present invention. As above suggested, this device might be placed around the outside of a single tube so that in effect it. would form :i casing thereforj or it might be cut into sections and uscd as a repair shoe. VlVhile I have shown eyelets and a lacing tape, it is obvious that the edges might be connected b vother means without departing from the prtnciplc of the invention.

` Vhat is claimed as new is:

The herein dcsribed liner comprising an imir section made up of two plies of fabric.
